"deja-clue" I like it :-)

I think the way to go is to look at some of the libstdc++/libio dejagnu
tests.  They know how to read from files and compare generated output to
an expected output file.

Which ones write files?  I haven't actually tried to run the fortran tests
for an embedded target yet.  But typically an embedded board doesn't have
a convienent way to do file I/O or to pass arguments to programs.  They may
not even have terminal I/O.  But they usually have stubs which allow linking
even though the target doesn't have I/O capabilities.


Simulators typically have enough brains to do I/O to a unix filesystem using
unix system call emulation.

I'd like us to start thinking about solving these problems (we don't have to
actually solve them now, just be aware of the problem and get some grey matter
thinking about solutions).
